Pricing a mural: square metre calculation and negotiation

01The foundation: price per square metre

The square-metre calculation is the starting point for any mural pricing. It lets you establish a floor below which you cannot go without working at a loss. This base price integrates three components.

The first component is material cost. Exterior murals require specific products: facade acrylic paint, UV-resistant varnish, bonding primer suited to the substrate. For a professional-quality exterior mural, material costs generally sit between 15 and 40 euros per square metre, depending on colour complexity and the number of coats needed. Brands used by professional muralists — Montana, Keim, Caparol — have variable but well-documented prices.

The second component is labour time. An experienced muralist paints on average between 2 and 6 square metres per day, depending on motif complexity. A flat colour area goes quickly; a large-scale realistic portrait advances slowly. The hourly rate you set should reflect your level of expertise. Professional muralists in France generally work on a basis of 300 to 600 euros per day, depending on their reputation and project complexity.

The third component covers ancillary costs: cherry picker or scaffolding rental, travel, accommodation if the site is remote, wall preparation (cleaning, filling, primer application). These costs are often underestimated by beginners yet represent a significant share of the budget. Renting a cherry picker costs between 150 and 400 euros per day depending on height.

02From raw calculation to artistic price

The square-metre price calculated above gives you an economic minimum. But you are not a house painter; you are an artist. Your mural price must also reflect the artistic value of your intervention.

Muralist Inti, from Chile, whose murals adorn facades worldwide, does not invoice his work per square metre like a tradesperson. His price reflects his reputation, the singularity of his visual universe, and the heritage value his mural brings to the building and neighbourhood. At a more accessible scale, the same principle applies: your price must reflect not just the work done but the value your signature brings to the place.

To establish this artistic price, you can apply a multiplier to your base price. This multiplier varies with your reputation, the commissioner's nature and the project's visibility. For an emerging artist, a multiplier of 1.5 to 2 is a reasonable starting point. For an established artist whose work is recognised in street art and mural circles, this multiplier can reach 3 or 4.

03The design phase: billing before painting

A common mistake by artists new to murals is not charging for the design phase. Before climbing onto a cherry picker, you spend hours drawing sketches, producing digital renders, adapting your project to the wall's constraints and the commissioner's wishes. This design work has value and must be paid for.

Standard practice among professional muralists is to charge the design phase separately, at 10 to 20 per cent of the total project budget. This separate billing has two advantages. It pays for your creative work even if the project does not go ahead. And it clarifies for the commissioner that design is a standalone task, not a bonus included in the execution price.

Muralist Seth (Julien Malland) has documented in his publications the importance of this design phase. His murals, found from Shanghai to Paris to New Delhi, always begin with detailed sketches and in-depth exchanges with local communities. This preparatory work is what distinguishes an artistic mural from a simple decorative painting.

04Negotiating without underselling

Negotiation is a moment where many artists lose their footing. The commissioner — whether a local authority, company, property developer or private individual — often has a precise budget and limited knowledge of a mural's real cost. They mentally compare your quote with a house painter's rate and find the difference hard to justify.

The key to negotiation is transparency. Present your quote in detail, with each item clearly identified: materials, equipment rental, design, execution (in number of days), finishing and guarantee. This transparency shows that your price results from calculation, not guesswork.

Never negotiate on your daily rate. If the commissioner's budget is below your quote, propose adjustments to the surface, motif complexity, or finishes. You can paint 30 square metres instead of 50, simplify certain zones of the motif, or forgo the protective varnish (explaining the consequences for durability). What you must not do is accept working below your value.

Spanish muralist Okuda San Miguel, known for his multicoloured geometric murals, built his career by refusing underpaid projects even when he was still little known. This stance built his reputation as a serious professional and attracted commissioners willing to pay the right price.

05Contracts: protecting your work

Every mural commission should be covered by a written contract. This contract does not need to be drafted by a lawyer, but it must cover the essential points.

The project description, accompanied by approved sketches, defines what you commit to producing. Dimensions, main colours, style: everything must be specified to prevent misunderstandings. The execution schedule, with start and end dates, protects both parties. The total price and payment terms are detailed: a deposit of 30 to 50 per cent on signing is standard in the profession. The balance is paid on delivery.

Copyright is crucial. Under French law, the artist retains moral rights over the work, even though the wall belongs to the commissioner. This means the mural cannot be altered or destroyed without your consent. Reproduction rights — photos of the mural used for commercial purposes — must also be clarified in the contract. The SNAP-CGT and the Maison des artistes publish model contracts suited to these situations.

06Evaluating longevity and context

A mural's price must also account for its longevity. An exterior mural exposed to the elements has a limited lifespan, generally between 5 and 15 years depending on climatic conditions and material quality. The commissioner must be informed of this reality. Some artists include a maintenance clause in their contract, providing for restoration at regular intervals.

The project's context also influences the price. A mural for a street art festival, where visibility is high but the budget modest, is not invoiced at the same rate as a private commission for a luxury hotel facade. The festival brings you visibility and network; the hotel brings revenue. Both have value, but not the same kind.

07From murals to your career

Mural painting is an excellent visibility lever for an artist. A 50-square-metre work on a building facade is seen by thousands of people daily, something no gallery exhibition can offer. This visibility has a value you can leverage in negotiation.

Document every mural with professional-quality photos and videos. This content feeds your portfolio, website and social media. It shows future commissioners what you can do and tells collectors that your work also exists at large scale. On Artedusa, muralists can use these images to enrich their profile and showcase the breadth of their practice, attracting collectors interested in more intimate formats.
